For your consideration, a vintage Olesen Illuminating Co. (Hollywood, California) stage light. The fixture is mountable, with a beefy clamp mounting, and adjustable--left/ right & up/ down. Further adjustments can be made to the light beam with four levers and a telescoping front lens. The UL tag for the fixture rates the lamp max at 750Watts; it has a 36" 3 wire cord with grounding plug. The light does work. Measurements: 18"L x 15.5"W with mounting bracket.
